、人手又はオートハンド等で行なう。In addition, some products such as rubber bushings for automobiles are integrally equipped with one or more metal cylinders, and vulcanization molding of such rubber products with metal cylinders requires an upper mold and It is also practiced to use a molding die that includes a lower mold and a split mold as a middle mold. In this case, set the required number of metal cylinders one by one on the support parts such as center pins and annular grooves provided on the lower mold, and overlap the middle mold and upper mold surrounding these metal cylinders on the lower mold. This allows the metal tube to be held in a capitium formed inside. Then, the obtained molded product is taken out manually or automatically after disassembling the mold and transporting the lower mold, middle mold, or middle mold to the outside.

ある。In this way, in a conventional molding die, there is a molding part that has a cavity and holds the molded product, and a pressurizing and heating part that supports the molding part, receives pressure, and heats the molded part. Therefore, in order to take the molded product and suspend it, the large lower mold, middle mold, or middle mold, which is also the pressurized and heated part, must be disassembled and transported to the outside.

に要する時間は一層長くなっていた。For this reason, the vulcanizing press does not operate during the considerable time required to take out the molded product, and the mold cools down during this time, resulting in a large loss of thermal energy. Moreover,
In order to improve efficiency, a plurality of products are often vulcanized and molded using one molding die, and in this case, the time required to take out the molded products becomes even longer.
更に、金属筒付きゴム製品の場合には、成形品を取り出

一層プレス稼動率が低下し、熱エネルギーの損失も大さ
くなっていた。Furthermore, in the case of rubber products with a metal tube, it is necessary to take time to set the metal tube in the lower mold after taking out the molded product.
The operating rate of the press further decreased, and the loss of thermal energy also increased.

能に形成した凹部とを有することを特徴とする。In order to achieve the above object, the molding mold of the present invention is such that the molding part of the mold required for molding is separated from other parts required for pressurization and heating and can be replaced, and the molding mold has a molding cavity. The invention is characterized in that it has a recess formed in at least one of the upper mold, the lower mold, and the middle mold so that the plug-in block can be fitted into the mold.
金属筒付きゴム成形品を加硫成形するための成形用金型

ィの一部は通常の如く上型１に形成しである。As shown in FIG. 1, this mold consists of an upper mold 1, a lower mold 2, a fitting split mold 3 fitted into a recess of the lower mold 2, and a fitting base 4. A fitting block is constituted by a fitting split mold 3 and a fitting base 4, and has a cavity for two rubber products having an inner cylinder 5 and an outer cylinder 6 inside, and a part of the cavity is attached to the upper mold 1 as usual. It is formed.

端を保持する円環状の溝１５とが設けられている。An upper insert mold 7 is bolted to the upper mold 1 in the central longitudinal direction, and an upper center pin 8 inserts and supports the upper end of the inner cylinder 5 into the upper insert mold 7, and an upper center pin 8 that supports the upper end of the outer cylinder 6. It is provided with a groove 9 for abutting and holding. The fitting split mold 3 is vertically divided into two parts along the longitudinal direction, and when put together, surrounds the outer periphery of the outer cylinder 6. In addition, as shown in FIG. 2, the fitting base 4 has a long and narrow plate shape, and has a lower center pin 14 for holding the lower end of the inner cylinder 5 and the lower end of the outer cylinder 6 on the upper surface 10, similarly to the upper mold 1. An annular groove 15 is provided.

長く幅広になっている。下型２は第１図に示すように、
嵌め込み基台４が嵌着する下側凹部】６と、嵌め込み割
型３が嵌着する上側凹部１７とを具えている。The side surface 12 along the longitudinal direction of the fitting base 4 is the lower surface 11
The inclined surface 12 is inclined so that the area of the upper surface 10 is smaller than the area of the upper surface 10, and therefore the cross section of the end surface 13 is in the shape of an inverted trapezoid. This shape with an inverted trapezoidal end face is the same for the above-mentioned fitting split mold 3, or the fitting split mold 3 is longer and wider in the inclined side direction than the fitting base 4. As shown in Fig. 1, the lower mold 2 is
It has a lower recess 6 into which the fitting base 4 is fitted, and an upper recess 17 into which the fitting split mold 3 is fitted.

注入し、加硫成形を行なうのである。The fitting base 4 on which the inner cylinder 5 and the outer cylinder 6 are set is fitted into the lower recess 16 of the opened lower mold 2, and then the fitting base 4 is fitted into the lower recess 16 of the opened lower mold 2.
is fitted into the upper recess 17. By pressing the upper mold 1 onto the lower mold 2, the entire cavity is formed, and at the same time,
The inner B5 and outer cylinder 6 are securely held inside. Therefore, as usual, raw rubber is injected into the cavity from an injection nozzle and vulcanization molding is performed.

しても良い。After vulcanization molding, the upper mold 1 and the lower mold 2 are separated, and the fitting split mold 3 and the fitting base 4 are separated from the lower mold 2 while grasping both end surfaces 13 protruding from the lower mold 2. Next, break the fitting split mold 3, fit the rubber product, and take the base 4 outside and hang it. Another fitting base 4 with an inner cylinder 5 and an outer cylinder 6 set in advance is fitted into the lower recess 16 of the empty lower mold 2,
Next, the 7PL mold 3 is fitted into the upper recess 17, and the same operations as described above are repeated to successively vulcanize and mold the rubber product. Incidentally, a large number of fitting split molds 3 may be prepared and used by replacing them one by one in the same manner as the fitting base 4.

ことかでさる。According to the present invention, the fitting block, which defines the molding part separately from the pressurized and heated part of the mold, is provided so that it can be fitted into the mold, so when removing the molded product and suspending it, only the fitting block is inserted into the mold. It would be better to take the carrier outside. Therefore, by preparing a large number of fitting blocks and sequentially fitting them into the mold, the vulcanizing press can be constantly operated regardless of the time required to take out the molded product, and the mold can be cooled. Since there is no downtime, the loss of thermal energy is reduced.

金型が型開きした状態で長時間停止していることがなく
、加硫プレスの稼動率を飛躍的に向上させ、また熱エネ
ルギー損失を大幅に低減させることができる。Furthermore, in the case of a mold for molding a rubber product with a metal tube as in the embodiment, by preparing a large number of fitting bases that are at least part of the fitting block, it is not only possible to take out the molded product, but also to make it more troublesome. Since the centering of the metal tube is performed independently of the vulcanization molding process, a separate fitting base with a metal tube set in advance can be easily fitted into the lower mold at the same time as the molded product is taken out, allowing molding to proceed as before. The mold does not remain open for long periods of time, dramatically improving the operating rate of the vulcanizing press and significantly reducing thermal energy loss.
更にまた、多少形状の異なる類似品種の加硫成形の場合
には、キャピテイを有する嵌め込みブロックのみを品種
毎に交換下れば良く、大きな下型及び上型を共用するこ
とが可能となり、能率的にもコスト的にも有利である。Furthermore, in the case of vulcanization molding of similar products with slightly different shapes, it is only necessary to replace the inset blocks with cavities for each product, making it possible to share the large lower mold and upper mold, which is more efficient. It is also advantageous in terms of cost.
